Flashing the BIOS 

Hi Drnlck48,

Welcome to the Community. I guess you can disable the touchpad in the Bios. Press F2 at the Dell Logo, move down to Post Behaviour and press Enter, select PS/2 Mouse, apply and save changes. This will disable the touchpad whenever you connect a mouse to your computer.

Hope this helps

Thank you

Royan - can I enable a touchpad this way too?  I want and need to use my e6510 occasionally without a mouse, but am unable to login into windows when I boot up as the touchpad is disabled.  How can I activate the touchpad when the mouse is not present?  Can I use the F2 setting you recommended above?

I have an E6510 and the touch pad is driving me nuts. I want to use touch pad when no mouse is plugged in and I followed your instructions by changing the Bios etc. your posted but after I select PS2 Mouse and save and reboot the touch pad is still working even when the mouse (USB) is plugged in.  What can I do to solve this problem?

 

Thanks
